IMPROVEMENT IN CLAMPS FOR MOSQUITNET FRAMES.

Specification forming part of Letters Patent No. P12295, dated February10,1874; application filed January 12, 1874.

To all whom it may concern: p

Beit known that LWILLARD M. WHITE, of Canton, Hartford county,Connecticut, have invented an Improved Clamp, of which the following isa specification, reference being had W taching the extension-rod, whichsupports the spreader, to the head or foot board ot' the bed, or thelike. It obviously may have other uses.

The invention consists in the combinations of parts set out in theclaims at the end of this specication, and what is not therein claimedis supposed, so far as this present invention is concerned, to be old.

The letter a indicates one leg of the clamp, and `b the other. From theformer project the mortised lugs al a2, designed to hold the lower jointof the extension-rod. The letter i indicates a thumb-screw, bearingagainst the extension-rod c. From the inner side of the leg aproject twospurs or teats, f f1, connected by the cross-pin f2. (Shown in dottedlines.) The leg b has a hook, b2, taking hold of the crossbarfz, therebypivoting the two legs together. In the top of the leg b there is pivotedthe swivel g, through which runs the thumb-screw h., its inner endbearing against the upper end of the leg a, whereby the feet ou thelower ends ofthe two legs can be pressed together as hard as desired, soas to grasp the head or foot 'board c. On the lower end of the leg a isa broad foot, s. On the lower end of the leg b is a similar foot, o. Oneor both these feet are hinged or pivoted to their respective legs. Ihave shown the foot o thus pivoted. The purpose of this is to make boththe feet atly embrace the two sides of the board c, whatever, withinobvious limits, be its `thickness, which would not be the case if beththe feet were rigidlyattached to their respective legs. On the lower endof the-leg b are cast two trunnions, t t. The foot 0 has bear= ings forthese two trunnions, and, being of some malleable metal, as malleablecast-iron, it has four projections, m m .fr x, cast upon it, which areafterward turned down upon the two trunnions, so as to secure the footto the leg, and yet leave a joint.

Of course, any common method of hinging the leg to the foot would answerthe purpose, but this' particular manner enables me to cheapen themanufacture of the article. The joint which connects the two legs isalso peculiar, and has its advantages. It is obvious that a common jointor pivot would answer the purpose, but the methodiI describe has twoadvantages: It enables me to cheapen the manufacture. of the article,and it enables me to take the two legs apart without trouble, so thatthey can be then packed in a smaller space, which is an importantmatter, as I de sign the whole mosquito-frame to be very portable, sothat it can be packed in the valises and bags of travelers.

I claim as my inventionl. The combination of the two clamp-legs a and bby means of the projections f f1, cross-bar f2, and the hook b2, wherebythe two legs are jointed, and yet readily separable, all substantiallyas shown and described, and for the purposes set forth.

2. The combination of the two clamp-legs a b, jointed together, andprovided with feet o s, one or both ot which are pivoted and adjustable,substantially as shown and described.

3. `The leg b and foot 0,' provided with a joint consisting of thetrunnions t t, bearings for I/Vitnesses z WM. EDGAR SIMoNDs, S. J.SmoNDs.
